Why read it?

26 authors picked Gideon the Ninth as one of their favorite books. Why do they recommend it?

This book is unhinged in the best way. I love Gideon’s unique voice. Around her is a deadly-serious necromancer murder mystery with interplanetary stakes, and she cares more about cracking dirty jokes and finally eating some warm food. Her relationship with her arch-nemesis/only friend Harrow leaps off the page.

I love the scene where they get into a pool so Harrow can finally confess to Gideon her darkest secret—so hot and so disturbing all at the same time. While this book isn’t technically a romance and the genre feels more like a horror fantasy set in space, I couldn’t resist…

I like to think I’m pretty good at guessing where a book is going to go—this is not the case with Gideon the Ninth. Every time I thought I had a grip on what was going on and where we were going, it took a turn. Every time I thought I had an idea of how I felt about a character, new lore dropped, and I fell in love (or in hate, or in a complicated love/hate thing that I have yet to figure out).

By the time I finished, I was torn between picking up the second book in…

From JW's list on LGBTQ speculative fiction.

With a cover like a Halloween fever dream, I expected a lot of otherworldly gothic creepiness, which this book delivered. What I didn’t expect was Gideon, an unforgettable character whose unapologetic frankness is like a shot of whisky in what could otherwise be an overwrought space opera. It’s a bit of stretch to call this historical fantasy, but I love that the world-building implies a complex backstory both for the characters and their world. Which sets up a wonderfully weird juxtaposition of ancient and modern.  Set in a feudal world, inhabited by undead necromancer lieges and their cavalier servants, I…

I was pleasantly surprised by just how weird this book is.

It is, as it was often marketed to me, “gay necromancers in space,” but it’s so much more than that. Disorientation, cerebral puzzles, and intricate worldbuilding permeate this whole book from chapter one. Tamsyn Muir is unapologetic about writing exactly what she wants, even if it’s outside a lot of readers’ comfort zones.

I found the strangeness of the societies, the challenges, and the mysteries woven into this book intriguing. It’s a murder mystery! In a high-stakes competition! With queer female main characters who have a lot of friction…

I love necromancers in space settings and opinionated characters with a strong voice, and Tamsyn Muir’s book did not disappoint. The book gradually ramps the action, emotion, and secrets until I couldn’t put it down. I was pulled into Gideon’s plight, first as she attempts to yet again escape indentured servitude to the necromancer Harrow, then as she helps Harrow navigate the deadly mysteries of Caanan House in exchange for her freedom.

I loved the fraught relationship between Harrow and Gideon as they navigated their complicated emotions and expectations of each other. The ending was particularly poignant, as their earlier…

Gideon the Ninth lit up the sky of the science fiction/fantasy world when it was published, launching the Locked Tomb series (which is ongoing, and great; third volume Nona the Ninth is especially lovely).

It's been described as "lesbian necromancers in space" but it's more "lesbian necromancer and swordsperson on various weird planets in the far future with a god-emperor who uses death magic to fight planet-sized spectral monsters...." for a start.

The whole series is enigmatic, complex, and laced through with humor, action, and yearning, but the first book is notable for the power of Gideon's voice.

From Tim's list on fantasy with women heroines.

Book cover of A Brush With Death

A Brush With Death by Jody Summers,

Former model Kira McGovern picks up the paint brushes of her youth and through an unexpected epiphany she decides to mix ashes of the deceased with her paints to produce tributes for grieving families.

Unexpectedly this leads to visions and images of the subjects of her work and terrifying changes…

It's a strange way to kick off a series of science fiction recommendations, but the first thing that drew me into this book is that it’s really more of a fantasy novel (that just happens to take place in space).

This book was my break from a long self-imposed laundry list of the classics, and it completely shook me up as a reader. I remembered what it was like to be so engrossed in a book that you’re staying up late in bed and ordering the next in the series when you’re only halfway through the first. I remembered what…

The oh-so-many blurts of “No, she won’t” moments before she did. The howls of laughter at Tamysyn’s outrageousness. The amazing, vivid, ingenious worldbuilding. 

The prying at where is she going with this? The action, the innuendo, the voice. The gender-bending freak show enculturation built up at a near epic levels. I cannot remember the last time a book entertained and intrigued me on so many levels.

Gideon the Ninth was recommended to me with its alluring tagline, “Lesbian necromancers in space.”

It took me a while to get into it, but when I did, I surprised myself with how invested I became in what initially sounded like a pretty silly premise.

This delightfully byzantine construction of a novel is full of easter eggs, of bizarre and gross bone magic, but also of children who are isolated and deprived. It is, in the end, about trauma and grief, about maintaining your dignity in impossible situations, with great pathos and dirty jokes.

I have had so many conversations…

Rescue Mountain by Rebecka Vigus,

Rusty Allen is an Iraqi War veteran with PTSD. He moves to his grandfather's cabin in the mountains to find some peace and go back to wilderness training.

He gets wrapped up in a kidnapping first, as a suspect and then as a guide. He tolerates the sheriff's deputy with…

Okay I’m fibbing a bit again with this one, but the books in this series are unabashedly queer and weird, and the method of space travel is like nothing you’ve ever seen.

These books fall much more clearly on the line of space fantasy than straight-up sci-fi, but they are wild and unforgettable reads. Gideon Nav is the titular character of Gideon the Ninth. She’s hilarious, goofy, loyal to an absolute fault, and utterly filthy. The other characters will break your heart and patch it up multiple times over the course of this book and the others.

Thankfully, most of…
